PROBLEM TO BE SOLVED: To provide a solar battery module which enables the increase in light condensing magnification.SOLUTION: According to an embodiment, a solar battery module comprising a solar cell panel, and a light-condensing material is provided. The solar cell panel has a solar battery cell. The light-condensing material reflects light incident from outside to irradiate the solar battery cell with the light. The light-condensing material has a first paraboloid and a second paraboloid. The first paraboloid reflects light incident at a first incident angle to irradiate a first portion within a range of the solar battery cell with the light. The second paraboloid reflects light incident at a second incident angle different from the first incident angle to irradiate a second portion within a range of the solar battery cell with the light, provided that the second portion is different from the first portion. When viewed from the solar battery cell, the first paraboloid is asymmetric to the second paraboloid.SELECTED DRAWING: Figure 1 |
